Help with this tough word problem?

Question

My friend asked me for help with her homework and we came to a problem neither one of us could answer, and we have asked everyone we know, nobody knows the answer, please help. The problem is:

You’re an anthropologist on a desert island studding its two tribes, on tribe always tells the truth, the other one always lies, but you can’t tell the difference between the two. One day your walking when you come to a fork in the road, on way goes to the Hilton you are staying at, the other goes to a deadly swamp; there is a native standing in-between the two roads, Your only aloud to ask him one question, if you ask two he will kill you with his spear. What question do you ask to find out what tribe he’s from and which road to take?

Answer 1

idk. thats hard i would just ask him which tribe he is from then go back to the hilton.

Answer 2

You ask one of the tribesmen this question.

"What would the other tribesman say if I aked if that was the right road to the Hilton."

The correct road will be the opposite of the one that the tribesman says.

If you are asking the tribesman who tells the truth all of the time, he knows that the liar will say that his road is safe, therefore the tribes men will say its safe.  hence you choose the other road.

If you are asking the tribesman who always lies, he will know that the tribesmen who tells the truth will say yes tha his road is the safe, so he lies to you and says "NO"  therefore the other road is correct.

True that you have no idea which tribesman you are speaking to when you ask the questions.  That's the whole idea, this question will get the correct answer out of either the liar or the truth sayer.

Cheers

Answer 3

"What would you say if I asked you which way to the Hilton?"

The truthteller would have told you right, and will say so.

The liar would have told you wrong, so must lie and tell you the correct answer.

You can't tell which tribe your subject is from, but you can get to the Hilton.
